CHIROPRACTIC TABLE.

Application filed April 12, 1920.

To all whom t may concern-J Be it known that I, WALTER B. Rnrnnr,residing at Dunkirk, in the county of Chautauqua and State of New York,have invented new and useful Improvements in Chiropractic Tables, ofwhich the following is a specification.

This invention relates to supporting tables used for medical or surgicalpurposes, and has for its object the provision of a table designed tosupport al human body in thoroughly relaxed condition so that thepatient will be in proper condition for manual manipulation of thejoints, vertebra-i, and the like, or any other manipulation forming apart of the chiropractic art as practised by Osteopaths and the like.

An important object is the provision of a table of this character whichincludes an abdominal support which is supported upon a plurality oflongitudinally disposed coil springs extending therebeneatli, thesprings being always under tension.

Another object is the provision of a device of this character whichincludes front and back supporting benches adapted to support the headand legs of a patient, these benches being longitudinally adjustabletoward or away from each other to accommodate patients of differentstatures, and which further includes an adjustable chest support, theposition of which may be varied irrespective of the position of theforward bench or head rest, the abdominal support above referred tobeing disposed between this chest support and the rear bench and-beingso mounted that it is absolutely independent of the adjustment of thebenches.

A further object is the provision of a device of this character in whichthe rear bench or leg supporting member includes a stationary and avertically swingably adjustable portion whereby certain positions of thebody upon the bench may be obtained.

A still further object is the provision of a device of this characterwhich includes a support adapted to remain permanently upon the floorand which pivotally supports the table proper whereby the table may beswung upwardly into substantially vertical position when desired.

An additional object is the provision of a table of this character whichwill be highly advantageous as providing the maxi- Speccation of LettersPatent.

inuin comfort for the patient, which will facilitate the manipulatingoperations, Which will be highly eflicient and durable in use, and ageneral improvement in the art.

With the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings inwhichl Figure 1 is a side elevation of the device in normal position,

Fig. 2 is a similar view showing the table proper swung upwardly,

Fig. 3 is a plan view with the parts arranged as shown in Fig. 1,

Fig. 1 is a top plan view of the stationary portion of the frame,

Fig. 5 is a bottom plan view of the movable. portion,

Fig. 6 is an end elevation,

Fig. 7 is a cross sectional view taken through the abdominal support,

Figs. 8, 9 and 10 are detail views showing the adjustability of thefront and rear benches and the chest support, and

Fig. 11 is a side elevation showing a modified form of the device inwhich only a stationary frame is employed. Referring more particularlyto the drawings, have shown my table as comprising a stationary baseincluding front and rear end castings 15 and 16 connected and spacedapart by longitudinal bai-s 17. The front casting 15 has its lowerportion enlarged and flattened to provide feet 18 and has its upperportion formed with a shoulder 19 for a purpose to be described. Therear casting 16 has its lower portion flattened to provide feet 20 whichare recessed at their upper edges, as shown at 21, for a purpose to bedescribed. The rear casting 16 is formed at its upper portion withspaced upwardly and rearwardly curved arms 22. The feet 18 and 2O areflattened and formed relatively large so that the device will not causeany damage to rugs or floors.

The movable portion of the device comprises a pair of spaced paralleltubes otr rods 23 which are connected at their forward ends by a casting24 which carries a depending arm 25 having a shoulder 26 engageable uponthe top of the casting 15 and having pivoted thereon a spring-pressedlatch 27 engageable beneath the shoulder 19 for holding the movableportion of the lde# vice down onto the stationary portion or base. Attheir rear ends the tubes 23 are connected by a casting 28 which isformed with one or more cup-like extensions 29. The recesses 21 in thecasting 15 are for the purpose of receiving the rear extremities of thetubes 23 when the movable portion of the device is in upright position,as shown in Fig. 2. At points spaced from their rear ends, the tubes 23carry castings 30 which are pivotally connected, as shown at 31, withthe extremities of the arms 22, this construction permitting the movableportion of the device to be swung in a vertical plane, as will beobvious.

Pivoted between the arms 22 by the pivots 31, are bars 32 which carrycylindrical projections 33 slidably engaged within the extensions 29 andcoil springs 34 are located within the extensions 29 and engage againstthe piston-like projections llt their ends the bars 32 are pivotallyconnected with a step 35 to the free end of which are connected braces36 which are connected at their other ends with the bars 32 adiacent thearms 22. Pivotally connected with an angular extension 37 on each sideof the casting 28 is a link 38 which has its other end connected with arod 39 connected with one end of a coil spring '40. The rear casting 16is provided with inclined recesses 41 within which the angularextensions 37 on the casting 28 may be engaged, as will be hereinafterexplained.

Slidablv disposed upon the tubes 23 is a casting 42 having sleeveportions 43 engaged upon the tubes and held in position by set screws44. Y rlhe numeral 45 designates broadly the rear bench of the devicewhich includes a cushion 46 supported upon boards or plates 47 and 48hingedly connected at 49. The board 47 carries kon its underside abracket 50 which is pivotally connected with the casting 42. Alsosecured upon the underside of the board 47 adjacent the hinge 49, isa'bracket 50 with which is pivotally connected one end of a curved bar52 which is slidable through the casting 42 and which is pivotallyconnected at its other end with a bracket 53 secured on the`underside ofa `board 47. TheV casting 42 carries a setscrew 54 which is engageablewith the arm 52 whereby to hold this arm in adjusted positions, for thepurpose of securing the bench 45 at different angles to the horizontal.

Adjustably mounted upon the tubes 23 near the forward ends thereof, is acasting 55 which includes sleeves 56 slidable upon the tubes 23 andhaving set-screws 57 engaging the tubes. The numeral 58 designates thehead rest which is cushioned and which carries on its underside abracket 59 pivotally connected with the casting 55 and which alsocarries on its underside a curved arm 60 slid-able through the casting55 and engaged by a set-screw 61 by means of which the head rest may beadjusted for disposition different angles to the horiacntal. lt will beobserved that by adjusting the casting 55 longitudinallyalong the tubes23, the position of the head rest with respect to the rear bench 45 maybe varied.

The numeral 62 designatesthe chest support which is cushioned and whichis supportedby a bracket 63 secured to the casting 55. Y

rllhe most important feature of the invention is the abdomen supportwhich comprises a cushion 64 disposed between the rear bench 45 and thechest support 62 and this cushion rests upon a plurality of coil springs65 which are secured to the free edge of the board 48 at one end andwhich are secured at their other ends to brackets 66 extending upwardlyfrom the casting 24.

in the use of the deviceit will be seen that the movable portion isdisposed in horizontal position upon the stationary portion and held insuch position by the latch 27. rlhe rear bench 45 and the head rest 53adjusted longitudinally upon the bars 23 to be disposed at the desireddistance apart to accommodate the patient. rihe head rest 58 is adjustedto the desired angular position and the board 47 of the rear bench isalso adjusted to the proper angular position to insure absolute comfortto the patient so as to produce or permit an absolute relaxation of allthe muscles so as to facilitate the manipulation of tie vertebrae andluinbars.V The springs 65 which support the abdominal cushion 64.

are always under tension and the tension may be increased or decreasedby shifting the rear bench along the tubes 23. This cushion will supportthe patients abdomen in a very comfortable position. lt. will beobserved that the springs 65 are absolutely uiatiected by the angularadjustment of the rear bench or by either the longitudinal or angularadjustment of the head rest. lt will be observed that owing to thesprings 34. the step 35 will be resiliently supported and may yield inproportion to the weight exerted thereon.

When the use of the device is not desired, the movable portion may beswung into substantially vertical position, as shown in Fig. 2, with therear extremities of the tubes 23 disposed within the recesses 21 andwith the angular extensions 37 engaging within the inclined recesses 41.

Referring to the modified form shown in Fig. 11, it will be seen thatthe structure of the essential. features is the same, the onlydifference being in the stationary support. In this form the stationarysupport comprises spaced tubes 73 similar to the tubes 23 supported byend castings 74 und 75 having {iatted feet 76. The rear bench, headrest, chest support, and abdomen support are exactly the same as in thepreviously described form but it will be observed that there is noprovision made for swinging the device into substantially uprightposition. The operation is of course the same as that of the previouslydescribed form.

TWhile I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claims.

Having thus described my invention, I claim:

l. A device of the character described comprising a pair of spacedparallel horizontal supporting rods, supports therefor.l a pair ofmembers longitudinally slidably adjustable upon said rods, a headsupport angularly adjustable upon one of said members, a chest supportadjacent said head support, a legs support carried by the other of saidmembers and including a relatively stationary section and a hingedsection, means for tilting said hinged section, and a spring supportedabdomen engaging member suspended between said head and legs supports.
